i generate some income from owning several websites that have steady, decent traffic. they are monetized with google adsense, amazon affiliate links, and a smattering of other, smaller ad-related services.
i think i'll net about $800 from these sites in october. funds go into my paypal account, and the balance (after expenses) goes into a business banking account i have set up. this revenue then funds either more website acquisitions, flows into my stock portfolio, or gets placed into real estate investments, in that order.
i only recently started this as a hobby (i wanted to do something profitable when i was at home), and you have to do some serious due diligence and sift through a lot of chaff, but the cash on cash return is quite remarkable. would i rely on this as a source of income to live off of, though? probably not...it's too risky for my personal tastes.
